|
Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
|
|
|
|
## Installation
|
|
|
|
This is a [Node.js](https://nodejs.org/en/) module available through the
|
|
[npm registry](https://www.npmjs.com/). Installation is done using the
|
|
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
|
|
|
|
```bash
|
|
$ npm install bytes
|
|
```
|
|
|
|
## Usage
|
|
|
|
```js
|
|
var bytes = require('bytes');
|
|
```
|
|
|
|
#### bytes.format(number value, [options]): string｜null
|
|
|
|
Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
|
|
rounded.
|
|
|
|
**Arguments**
|
|
|
|
| Name | Type | Description |
|
|
|---------|----------|--------------------|
|
|
| value | `number` | Value in bytes |
|
|
| options | `Object` | Conversion options |
|
|
|
|
**Options**
|
|
|
|
| Property | Type | Description |
|
|
|-------------------|--------|-----------------------------------------------------------------------------------------|
|
|
| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
|
|
| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
|
|
| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `.`... Default value to `''`. |
|
|
| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
|
|
| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
|
|
|
|
**Returns**
|
|
|
|
| Name | Type | Description |
|
|
|---------|------------------|-------------------------------------------------|
|
|
| results | `string`｜`null` | Return null upon error. String value otherwise. |
|
|
|
|
**Example**
|
|
|
|
```js
|
|
bytes(1024);
|
|
// output: '1KB'
|
|
|
|
bytes(1000);
|
|
// output: '1000B'
|
|
|
|
bytes(1000, {thousandsSeparator: ' '});
|
|
// output: '1 000B'
|
|
|
|
bytes(1024 * 1.7, {decimalPlaces: 0});
|
|
// output: '2KB'
|
|
|
|
bytes(1024, {unitSeparator: ' '});
|
|
// output: '1 KB'
|
|
|
|
```
|
|
|
|
#### bytes.parse(string｜number value): number｜null
|
|
|
|
Parse the string value into an integer in bytes. If no unit is given, or `value`
|
|
is a number, it is assumed the value is in bytes.
|
|
|
|
Supported units and abbreviations are as follows and are case-insensitive:
|
|
|
|
* `b` for bytes
|
|
* `kb` for kilobytes
|
|
* `mb` for megabytes
|
|
* `gb` for gigabytes
|
|
* `tb` for terabytes
|
|
|
|
The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
|
|
|
|
**Arguments**
|
|
|
|
| Name | Type | Description |
|
|
|---------------|--------|--------------------|
|
|
| value | `string`｜`number` | String to parse, or number in bytes. |
|
|
|
|
**Returns**
|
|
|
|
| Name | Type | Description |
|
|
|---------|-------------|-------------------------|
|
|
| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
|
|
|
|
**Example**
|
|
|
|
```js
|
|
bytes('1KB');
|
|
// output: 1024
|
|
|
|
bytes('1024');
|
|
// output: 1024
|
|
|
|
bytes(1024);
|
|
// output: 1024
|
|
```
